Tips: The role of isolation switch

1. After opening, establish a reliable insulation gap, and separate the equipment or lines that need to be overhauled from the power supply with an obvious disconnection point to ensure the safety of overhaul personnel and equipment.
2. The isolating switch and the circuit breaker cooperate to carry out the switching operation to change the operation mode.
3. It can be used to divide and combine small currents in the circuit, such as the charging current of bushings, busbars, connectors, short cables, the capacitance current of the switch voltage equalization capacitor, the circulating current when the double busbar is switched, and the excitation current of the voltage transformer Wait.
4. According to the specific conditions of different structure types, it can be used to divide and combine the no-load excitation current of a certain capacity transformer.
